I don't think the screen is the issue here. If you think the battery life is far worse than what we have today its rather a battery issue. But personally, I think what is the base of the issue is what attract users today. Slim... Ness. That the source.

Personally. Your minds need to get used to the thought of 1080p with a battery of 2xxx. No one would complain about that screen battery composition in 6 month it reaching a standard.

Wait for some real tests please. And get the 1080p screens in to your head.
